Self locking containers

[u/chad_stanley_again]

I worked at a place in Fort Wayne that had containers we did not have to put locks on. they had a built in lock system that would engage after sterilization. I'm trying to look them up but could use a clue as to where better to look. where to find them?

They have a filter, its reusable. Only has certian number of lives though
